Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical apparatus and instruments, and particularly relates to a bone flap decompression post-adjustable bone window protection device for brain trauma bone window protection. BACKGROUND

[0002] After craniocerebral surgery, brain swelling is often serious, and bone flap decompression is often needed to let the swollen brain tissue swell out of the bone window to prevent high intracranial pressure from compressing the brainstem and endangering life. However, after bone flap decompression, the protection of the bone window is not in place, which may cause damage to the brain tissue around the bone window, and may also cause the brain tissue to swell excessively, which cannot be reset normally in the later period, bringing difficulties to clinical treatment and affecting the quality of life of patients.

[0003] The bone window can be divided into three periods according to clinical treatment: the first period, i.e. the edema aggravation period of about one week, needs to be fully decompressed to let the brain tissue swell out of the bone window as much as possible to prevent the brainstem from being compressed and endangering life. The second period, i.e. the edema stabilization period of about one to two weeks, is relatively stable, and prevents the bone window brain tissue from further swelling. The third period, i.e. the edema dissipation period after about three weeks, is gradually disappearing, and the brain tissue is gradually reset, and the swollen brain tissue is gradually reset with external force assistance, and the nerve function is protected.

[0004] At present, there are methods such as skull protection cap or elastic bandage compression for decompression bone window protection, but there are still the following problems: 1. At present, the bone window protection cap is generally made by 3D printing technology, and the corresponding defective skull protection plate is made by the symmetry method to protect the bone window, which is mainly for the bone window protection after the brain tissue is reset after bone flap decompression. The disadvantage is that it cannot protect the bone window in the early stage, and it cannot achieve the protection of the gradual return of the swollen brain tissue. 2. The elastic bandage protection bone window method can effectively prevent the excessive swelling of the brain tissue. However, it also has the problems of not being able to protect the bone window in the early stage, and not being able to return the swollen brain tissue gradually and evenly under stress in the process of returning the brain tissue. The clinical effect is not good. 3. At present, the bone window protection device cannot change with the change of the shape of the swollen brain tissue when the brain tissue is moderately compressed and returned, and cannot accurately stress the swollen brain tissue and effectively return it. 4. When the elastic bandage compresses the bone window to return the brain tissue, the gradual compression is not fine enough, and the controllability is not strong. CONTENT OF THE UTILITY MODEL
